Self-Assembly of Dendrimers by Slippage
A dendrimer with rotaxane-like characteristics has been assembled under thermodynamic control from complementary wedge-shaped precursors by slippage in CH2Cl2. The driving force for the self-assembly process is the molecular recognition that exists as a result of [N+−H···O] and [C−H···O] hydrogen bo...

| Zusammenfassung: | A dendrimer with rotaxane-like characteristics has been assembled under thermodynamic control from complementary wedge-shaped precursors by slippage in CH2Cl2. The driving force for the self-assembly process is the molecular recognition that exists as a result of [N+−H···O] and [C−H···O] hydrogen bonds between an NH2 + center in one Fréchet-type benzyl ether wedge and a dibenzo[24]crown-8 unit that links the other two such wedges. |
